Updated versions of these OXPs (well, 'OXZs') are available via the in-game update manager.

Interstellar Tweaks I've pretty much re-written from scratch, because my coding style has become less awful and I've made some optimisations and adjustements and fixed some bugs. I've made many coding changes in the other OXPs too, but it is only in Interstellar Tweaks that you are like to see changes, in the form of (1) performance improvements, (2) some slight behavioural changes. You might want to note as well that, with this OXP, what one sees in interstellar space depends somewhat on where you start from. That is: if you want to see new scenarios, try changing the systems you are jumping between. A few bits of interstellar space - bits between certain systems - even have nicely-coloured skies.

If you discover any bugs, please report them in this thread.

PS: I'd introduced the 'Delux-o-Tank' version of the 3G ship previously, right? If not, I recommend you install the updated pack and buy one!

Thanks for the report. Now, I develop the OXP on Windows (unfortunately; I may shift to Linux) and it's hard to know what's going on in Windows. Or at least I am having trouble with the OXP verifier. Still, I got it to run (it runs from the command line, but not from Windows Explorer . .) and all seems OK, and I can run the OXP from my system without errors.

I suggest that you: remove the OXP entirely - by using the in-game manager, and by checking the OXP is not in your OXP folder(s) - and reinstall it and then, if the problem persists, tell me the following.

Macs are notoriously picky with plist files. I had a look at the shipdata.plist and missiontext.plist files in the latest InterstellarTweaks, and this is what I found.shipdata.plist-- Missing semi-colons (";") at the end of these lines: 18, 34, 46, 58, 71, 82, 91, 99, 110, 137, 147, 156, 175, 187, 208, 218, 233, 2547missiontest.plist-- Missing semi-colon at the end of line 9.
I was just eye-balling these so I might have missed a couple.
Hope that helps a bit.
